specification and illustrated in the accompa-' nying drawings that form part of the same.

The invention consists essentially of the novel formation of 4disk closure whereby a lug is formed on one side and so arranged as to bend easily on being inserted in the bottle and be packed at the corners.

The objects of the invention are to devise a means of facilitating the removal of card disks, particularly from milk bottles, .without spilling any part of the contents, todo this and not leave any aperture through which the milk will leak or dust enter and generally to provide a cheap and serviceable closuren for milk and other bottles.

In the drawing, Figure 1 is a plan view of a disk closure showing this invention.

Fig. 2 is an enlarged fragmentary view showing the particular formation of the lug. j

Fig. 3 is a perspective view of a'bottle neck showing the card closure in place.

Fig. 4 is a fragmentary view showing the positions of the lug and adjacent corners of the disk in relation to the bottle neck.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, the disk 1 of card board or other suitable material is cut slits 4c are made, said sllts terminating at 1 points on the edge of the line of continuation of the circle through said lug.

It will be thus seen that the lug 2 .will

be'more easily turned upwardly on being inserted in the neck of the bottle and that the fillets 3 cut away by the slits 4:, being very small pointed ends of card board, will crush inwardly and provide a natural packing for the side of the hinge, where the lug turns upwardly.

- All such lugs in milk bottles hitherto have left an aperture on being inserted in the bottle, but this is easy to vbend and has the corners formed by the bend illed with the crushed card, which becomes more satisfactory the longer the milk is in the bottle, as the soaking of the card material swells it, especially at the edge wherefrom the fillets are cut away.

In the use of the invention the closure is inserted in the customary manner and the lug turns upwardly or is previously turned and the llets as explained crush to the neck wall beside the lug. `To remove the closure the lug is grasped and the disk pulled out.

What 1 claim is 1. 1n a bottle closure, a disk having a lug projecting from the edge thereof and .said lug having cuts extending inwardly from the side edges of the lug and terminating at the continuation line of the edge through the lug.

2. 1n a bottle cap, a piece of cardboard having a lug projecting therefrom and {illets formed inthe corners produced by they intersection of the sides of the lug and the outer edge of the cap, said fillets being separated from the lug by oblique cuts which terminate at the continuation line of the edge of the cap through the lug.

Signed at the city of Montreal, in Canada this 12th day of May1916.
